SMOKING PIPE.

Application filed June 29,

This invention relates to smoking pipes and more particularly to animproved stem construction, one object of the invention being to providea pipe which may be very easily cleaned it the stem becomes choked withtobacco and nicotine.

Another object of the invention is to provide the stem with a linerwhich may be readily removed therefrom when it is desired to clean thepipe and in addition to constituting a removable liner also-serves as acoupling to detachably connect a mouthpiece with the pipe stem.

Another object 01 the invention is to provide a liner formed ofseparable sections which may be firmly held in operative relation toeach other but readilytaken apart when withdrawn from the pipe stem.

This invention is illustrated in the accompanying drawing, whereinFigure l is a longitudinal sectional view through the improved pipe;

Fig. 2 is a perspective view of the liner and a sleeve which holds thecompanion sections thereof assembled;

Fig. 3 is a transverse sectional view taken on the line 3-3 of Fig. 1.

The pipe forming the subject-matter of this invention includes a bowl 1which may be of any desired size and configuration and is provided witha stem 2 which projects from its lower portion and is formed with anenlarged bore 3 communicating with the bottom of the bowl. Themouth-piece 4 is also of a conventional construction and formed with theusual bore or smoke passage 5. At its forward end the mouth-piece isreduced to provide a neck extension 6 surrounded at its rear end by anannular abutment shoulder 7. In order to connect the mouth-piece withthe stem, there has been provided a coupling which in addition tojoining the mouth-piece to the stem also con stitutes a removable lineror filler for the stem. This coupling is constructed as shown in Fig. 2and comprises companion sections 8 which may he formed of any suitablematerial and are separable. The two sections when disposed incooperating relation to each other, form a tube 9 which hits snugly1926. Serial No. 119,498.

within the bore 3 of the stem and has its bore 10 axially alined withthe bore 5 of the mouth-piece and communicating with the bottom of thebowl 1. The outer end portion of the companion sections 8 are enlarged,as shown at 11, and cooperate to form a socket. 12 which at its forwardend abuts the rear end of the stem 2. The socket tapers rearwardly, asshown in Fig. 1, so that it may have wedging fit into a tapered sleeve13. The sleeve 13 is formed of metal and at its rear end is providedwith an inwardly extending annular flange 14 which overlaps the rearedge of the socket and is adapted to be firmly gripped between the rearedge of the socket and the abutment shoulder 7 when the neck 6 of themouth-piece is fitted into the socket. The neck fits snugly into thesocket and from an inspection of Fig. 1 it will be readily seen that atight joint will be formed and leakage prevented which would interferewith proper drawing of the pipe. The sleeve 13 may terminate at theforward end of the socket, but in the preferred form it is extendedsomewhat and has overlapping engagement with the pipe stem so thatdanger of the liner being broken at the junction of the tubular portion9 with the socket 12 will be eliminated.

By having the pipe constructed as illustrated it can be readilycleanedas it is merely necessary to grasp the sleeve 13 with the lingersof one hand and the bowl and stem portion of the pipe with the otherhand and exert a pulling action towithdraw the liner from the stem.After the liner has been withdrawn, the mouth-piece may be extractedfrom the socket and the sleeve removed. The two sections of the linermay then be separated and thoroughlycleaned. After they have beencleaned, the coupling may be reassembled and engaged with themouth-piece and fitted into the pipe stem. It only the mouth-piece needscleaning, it may be removed from the socket without withdrawing thecoupling from the stem.

Having thus described the invention, I claim:

A smoking pipe comprising abowl, a stem extending therefrom and having abore comtil) vided with an inwardly extending annular flange overlappingthe rear end of the liner and a mouth-piece haying a reduced forward 10end fitted into said liner and an annular shoulder engaging the flangeof said sleeve. In testimony whereof I afiix my signature.
